[SOLVED] Just stating out, gcc issues

kc3 · 05-11-2010, 10:20 AM

Okay, everytime I've attempted this I keep getting problems compiling gcc and I can't get it to work, someone please help

There's a lot more text but the forums won't let me post that long of a post so I hope this is enough.

Hi,

please always post which version you are trying to build and which chapter you are. I assume LFS 6.6 chapter 5.5.1? Also post which commands you issued, i.e. as you typed them into the console. Do not just copy+paste them from the book. It is also better to just post the last 20 lines of the log before the error occurred. The rest of the log can be uploaded as attachment if necessary.

As for your problem it appears that you used /mnt/lfs/tools/ as build directory. You are not supposed to do that. You should keep the source in /mnt/lfs/sources/gcc/ and compile gcc in /mnt/lfs/sources/gcc-build/.

Oh okay, sorry about all the text... So I tried it again, would what directory I have it in really change if it works or not? Anyways this is what I typed

Quote:

lfs:/mnt/lfs/sources/gcc-build$ ./configure \
> --target=$LFS_TGT --prefix=/tools \
> --disable-nls --disable-shared --disable-multilib \
> --disable-decimal-float --disable-threads \
> --disable-libmudflap --disable-libssp \
> --disable-libgomp --enable-languages=c

and so far that worked, than I tried just make and this is now the output

Quote:

And yes I am in chapter 5.5.1 of the 6.6 version. Also for where to build it the book says outside the source directory in it's own directory and well, I did that one too and it still didn't work, I had tried different three directories and none worked.

Hi,

did you also untar mpfr and gmp in gcc's source directory before you executed configure? Which host system are you using? If it is not the liveCD, have you checked all the requirements?

Also, when you build binutils in the previous chapter, did you also use /mnt/lfs/tools as build directory?

No I didn't use that as the build directory, I'm using Slackware 13 as the host system and I did check and yes gmp and mpfr are in the gcc directory

Ok, however since you used /mnt/lfs/tools as build directory it is probably corrupted. So it is best to start completely over with chapter 5, reformating the build partition. Make sure you have a copy of the source-tars on another partition available.
Only use /lfs/mnt/sources/ to keep your source and build directories in, e.g. binutils's source resides in
/mnt/lfs/binutils-2.20/
and the build directory
/mnt/lfs/binutils-build/
If you make a mistake always start with a fresh untarred source of the package and a fresh build directory - if one is needed for that package.

In the meantime you can upload the output of the configure script as attachment. Not sure if your error is a follow-up of trying to recompile gcc from a 'used' source or if something else is up.

Okay, I will try that, thanks

[Update] Yep that worked, I appreciate the help

After extracting gcc the folder structure will be as follows
gcc-4.4.6
gcc-4.4.6/gcc

If you directly go inside gcc-4.4.6/gcc and try to do ./configure and compile(make) from there then you will encounter below problem
build/genmodes -h > tmp-modes.h
/bin/sh: build/genmodes: No such file or directory

Solution is do ./configure and make from gcc-4.4.6 and no errors will be shown related to genmodes. This will compile all modules including gcc. You may have to install mpfr and gmp modules which are needed by gcc if any error shown by ./configure
